[0031] Example 1, see Figure 1 , Figure 1 This is a schematic diagram of one embodiment of a water temperature sensing device provided in this application, as shown below. Figure 1 As shown, the water temperature sensing device includes a device body 10, wherein the device body 10 is provided with a position detection component 101, an axisymmetric display component 102, and a control component 103; the control component 103 is electrically connected to the position detection component 101 and the axisymmetric display component 102 respectively; wherein, the control component 103 is used to detect the pin status of the position detection component 101, determine the installation orientation information of the device body 10 based on the pin status, and control the axisymmetric display component 102 to automatically adjust the display direction of the water temperature information based on the installation orientation information.

[0032] like Figure 2 As shown, Figure 2 This is a schematic diagram of another embodiment of a water temperature sensing device provided in this application.

[0033] In one embodiment, the device body 10 is installed at the outlet of the mixing valve.

[0034] In one embodiment, the device body 10 is further provided with a water flow power generation component 104; wherein the water flow power generation component 104 is connected to the water outlet channel of the device body 10; the water flow power generation component 104 is used to supply power to the control component 103.

[0035] Specifically, the water flow power generation component 104 mainly includes a water flow generator and a power supply circuit.

[0036] Specifically, the water flow generator component 104 is connected to the water outlet channel of the device body 10, that is, the water inlet and outlet of the water flow generator are connected to the water path of the water outlet channel; when the user opens the mixing valve to use hot water, the water will flow through the water outlet channel and the inside of the water flow generator in sequence, forming a power source to drive the power generation.

[0037] Specifically, when water flows through the outlet channel and passes through the water flow generator, the kinetic energy of the water flow drives the magnetic rotor inside the generator to rotate and generate induced electrical energy. This electrical energy is converted into stable direct current after being rectified, filtered and regulated by the power supply circuit, and is used to provide working voltage for the control component 103 and other electrical components of the device body 10.

[0038] In one embodiment, the device body 10 is further provided with a temperature detection component 105, wherein the temperature detection component 105 is connected to the water outlet channel of the device body 10 and is used to collect water temperature information in real time; the temperature detection component 105 is also electrically connected to the control component 103; the control component 103 controls the axisymmetric display component 102 to display the water temperature information.

[0039] Specifically, the temperature detection component 105 includes a temperature sensor, such as a temperature probe.

[0040] Specifically, the temperature detection component 105 is directly connected to the water outlet channel of the device body 10. Based on the method of inserting the temperature probe into or close to the water flow path inside the water outlet channel, it is ensured that the temperature detection component 105 can directly contact the hot water flowing through it, thereby sensing the water temperature information in real time and accurately.

[0041] Specifically, the temperature detection component 105 also establishes an electrical connection with the control component 103 through the Bluetooth two-way communication module 106 built into the device body 10, so that the collected water temperature information can be transmitted to the control component 103 in real time.

[0042] Specifically, when the temperature detection component 105 detects water temperature, it directly contacts the water flow, converts the detected water temperature physical quantity into a corresponding voltage signal, and transmits the voltage signal to the control component 103. After receiving the voltage signal, the control component 103 performs analog-to-digital conversion on the voltage signal to obtain specific water temperature information.

[0043] In one embodiment, the axisymmetric display component 102 is an axisymmetric dual 8LED digital screen; wherein, the axisymmetric dual 8LED digital screen is composed of four groups of light-emitting components, wherein each light-emitting component is composed of the same number of LED light-emitting segments; such as Figure 3 As shown, Figure 3This is a schematic diagram of the structure of an axisymmetric display component 102 according to an embodiment of this application.

[0044] Preferably, each light-emitting component consists of four LED light-emitting segments.

[0045] Specifically, the four sets of light-emitting components are symmetrically distributed around the central axis of the axially symmetrical dual 8 LED digital screen, forming a complete display structure of the "double 8" character. Two of the four sets of light-emitting components correspond to the tens digit "8" character of the water temperature value, and the other two sets correspond to the units digit "8" character. The overall layout of the tens and units digit "8" characters also satisfies the axial symmetry characteristic. This design allows the relative position and light-emitting segment layout of the four sets of light-emitting components to maintain visual symmetry even after the axially symmetrical dual 8 LED digital screen is rotated 90°, 180°, and 270° around the central axis.

[0046] Preferably, the axisymmetric display component 102 can also be an LED dot matrix screen.

[0047] Specifically, the axisymmetric display component 102 establishes an electrical connection with the control component 103 through the Bluetooth bidirectional communication module 106; the control component 103 controls the lighting and extinguishing of each LED light-emitting segment in the four groups of light-emitting components in the axisymmetric display component 102 through the driving circuit.

[0048] Specifically, after the temperature detection component 105 collects water temperature information and transmits it to the control component 103, the control component 103 first converts the water temperature data into specific numbers, such as "3" and "6" in 36℃, and controls the axisymmetric display component 102 to display the water temperature information.

[0049] In one embodiment, the orientation detection component 101 is a four-way detection switch; the four-way detection switch includes four conductive metal springs, conductive balls, and metal pins corresponding to each of the conductive metal springs; when the device body 10 is installed in any of the up, down, left, or right directions, the conductive balls are used to conduct the two conductive metal springs in the lower position of the current installation position under the action of gravity.

[0050] Preferably, the four-way detection switch is a four-way ball switch.

[0051] Specifically, four conductive metal springs are arranged inside the switch with the center of the device body 10 as the symmetrical reference, and in a preset orientation, they correspond to the low-position areas of the four possible installation orientations of the device, forming a symmetrically distributed detection structure. For example, they are set at the four apex corners inside the four-way detection switch, so that the low position of each installation orientation corresponds to two conductive metal springs. The conductive ball is made of a metal material with good conductivity and can roll freely within the limited space inside the four-way detection switch. Its diameter matches the spacing of the conductive metal springs, ensuring that when the device is installed in any orientation, it can stably contact and conduct only the two conductive metal springs in the low position of the installation orientation. Each conductive metal spring is independently connected to a corresponding metal pin, and the metal pin is connected to the detection interface of the control component 103 so that the control component 103 can detect the pin status of the orientation detection component 101.

[0052] Example Explanation: When the water temperature sensor is installed at different positions of the mixing valve outlet, such as up, down, left, and right, the device body 10 forms a specific spatial posture due to the difference in installation angle. At this time, gravity will drive the conductive ball to roll towards the lowest position area in the current posture. For example, when the device body 10 is installed at the lower outlet position, the conductive ball rolls to the corresponding low position area under the action of gravity, and contacts and conducts electricity with the two conductive metal springs in that area. If it is installed at the left outlet position, the conductive ball rolls to the low position area on the left, and conducts electricity with the two conductive metal springs on the left. This displacement of the conductive ball position caused by the change of installation orientation is directly converted into a change in the circuit on / off state. The two conductive metal springs that are conducted form a conductive path through the conductive ball, causing their corresponding metal pins to output a conduction signal.

[0053] Preferably, the number of conductive metal springs can be any number other than four, such as multiples of four.

[0054] In one embodiment, the control component 103 is used to detect the pin status of the orientation detection component 101 and determine the installation orientation information of the device body 10 based on the pin status. Specifically, the control component 103 pre-stores a mapping table of metal pin conduction combinations and installation orientations. The control component 103 detects the pin status of the orientation detection component 101, determines the target metal pin combination in the conduction state, matches the target metal pin combination with the metal pin conduction combinations set in the mapping table, and uses the installation orientation corresponding to the matched target metal pin conduction combination as the installation orientation information of the device body 10.

[0055] Specifically, since each of the four positions corresponds to two conductive metal springs, a unique combination of metal pins will be formed under different installation positions. For example, the four conductive metal springs are... At this time, four combinations are formed, namely AB, AC, CD, and BD, which correspond to the four directions respectively. This forms a mapping table between the metal pin conduction combinations and the installation directions, including AB-up, AC-left, CD-down, and BD-right, ensuring that each installation direction has a unique metal pin conduction combination as an identifier.

[0056] Specifically, the control component 103 monitors the on / off state of each metal pin in real time through electrical connection with each metal pin. For example, by detecting the level change of the metal pin, it determines whether the metal pin is conducting, and based on the detection result, it selects the metal pins in the conducting state to form a target metal pin group.

[0057] Specifically, after acquiring the target metal pin combination, the control component 103 enters the matching stage, comparing the real-time detected target combination with the pre-stored mapping table. Since each installation orientation in the mapping table corresponds to a unique pin conduction combination, the control component 103 can determine the orientation information corresponding to the current target combination through precise matching. For example, if the detected target combination is completely consistent with the preset metal pin conduction combination for the left water outlet orientation in the mapping table, the control component 103 determines that the installation orientation of the device body 10 is left. This process does not require manual intervention from the user and is completely completed automatically by the control component 103. The final determined installation orientation information will be directly used to drive the axisymmetric display component 102 to adjust the display direction of the water temperature information, ensuring that the display content is adapted to the installation orientation.

[0058] In one embodiment, the device body 10 is further provided with a light strip display component 107, wherein the light strip display component 107 is composed of a plurality of lamp blocks; the light strip display component 107 is electrically connected to the control component 103.

[0059] Specifically, the light strip display component 107 is composed of multiple independent light blocks arranged in sequence, wherein the number of light blocks can be set according to design requirements; preferably, the number of light blocks is 10.

[0060] Specifically, the temperature detection component 105 is electrically connected to the control component 103 via a Bluetooth bidirectional communication module 106.

[0061] In one embodiment, the control component 103 is further configured to receive the remaining hot water volume value, determine the number of light strip displays based on the remaining hot water volume value, and control the light strip display component 107 to light up the corresponding number of light blocks based on the number of light strip displays.

[0062] Specifically, the device body 10 is equipped with a hot water volume display module, which is electrically connected to the control component 103 via a Bluetooth two-way communication module 106; the hot water volume display module is used to send the remaining hot water volume value to the control component 103.

[0063] Specifically, after receiving the remaining hot water volume value transmitted by the hot water volume display module, the control component 103 determines the number of light strips to be lit according to a preset ratio: for example, 10 light strips are lit when the remaining hot water volume is 100%, 5 light strips are lit when it is 50%, and so on. The number of light strips directly reflects the proportion of remaining hot water. This proportional display method allows users to quickly determine whether there is enough remaining hot water, solving the problem of inconvenient viewing of the display on the body of traditional water heaters.

[0064] In one embodiment, the control component 103 also controls the light strip display component 107 to automatically adjust the lighting direction of the lamp blocks based on the installation orientation information. This orientation adaptation design ensures that users can comfortably view the light strip display status in any installation scenario, further enhancing the human-computer interaction experience.

[0065] Specifically, when the installation orientation information is either up or down, the lighting direction of the lamp blocks in the light strip display component 107 is from top to bottom or from bottom to top.

[0066] Specifically, when the installation orientation information is either left or right, the lighting direction of the lamp blocks in the light strip display component 107 is from left to right or from right to left.

[0067] In one embodiment, the device body 10 is further provided with a button assembly 108; the button assembly 108 includes, but is not limited to, a tactile button or a spring-loaded touch button.

[0068] Specifically, the number of button components 108 can be one or more; different functions can be interacted through single click, double click, and long press.

[0069] Example 2, see Figure 4 , Figure 4 This is a flowchart illustrating one embodiment of a method for adjusting the display direction of a water temperature sensing device provided in this application. Figure 4 As shown, the method includes steps 401-403, as detailed below:

[0070] Step 401: Detect the pin status of the orientation detection component.

[0071] Step 402: Determine the installation orientation information of the device body based on the pin status.

[0072] Step 402: Based on the installation orientation information, control the axisymmetric display component to automatically adjust the display direction of the water temperature information.

[0073] In one embodiment, the control component pre-stores a mapping table of metal pin conduction combinations and installation orientations; the step of detecting the pin state of the orientation detection component and determining the installation orientation information of the device body based on the pin state specifically includes: determining a target metal pin combination in a conduction state by detecting the pin state of the orientation detection component, matching the target metal pin combination with the metal pin conduction combinations set in the mapping table, and using the installation orientation corresponding to the matched target metal pin conduction combination as the installation orientation information of the device body.

[0074] In one embodiment, the control component monitors the on / off state of each metal pin in real time through electrical connection with each metal pin. For example, by detecting the level change of the metal pin, it determines whether the metal pin is conducting, and based on the detection result, it selects the metal pins in the conducting state to form a target metal pin group.

This process does not require manual intervention from the user and is completed automatically by the control component. The final determined installation orientation information will be directly used to drive the axisymmetric display component to adjust the display direction of the water temperature information, ensuring that the display content is adapted to the installation orientation.

[0076] In one embodiment, the number of light strip displays is determined based on the received remaining hot water volume; based on the number of light strip displays, the light strip display component is controlled to light up a corresponding number of lamp blocks; based on the installation orientation information, the light strip display component is controlled to automatically adjust the lighting direction of the lamp blocks.

[0077] Specifically, after receiving the remaining hot water volume value transmitted by the hot water volume display module, the control component determines the number of light strips to be lit according to a preset ratio: for example, 10 light strips are lit when the remaining hot water volume is 100%, 5 light strips are lit when it is 50%, and so on. The number of light strips directly reflects the remaining hot water volume ratio. This proportional display method allows users to quickly determine whether there is enough hot water left, solving the problem of inconvenient viewing of the display on the body of traditional water heaters.
